wxnnow SGREEN Filed Dec. 17. 1929 Alfed '6.Nmfdmm'ken m' A mw Patented May 24, 1932 i UNITED STATES- PATENToFl-ICE l' My invention relates to window screens and particularly to window screens adapted to be used in conjunction with double hung windows and has for its object to provide a fastener for the screen by means of which the same may be readily rendered operative or mo eratlve.

in providinga fastener for de tachablysecuring the free end ofthe screen to the window frame. A still further object of the invention' resides in constructing said fastener ivith yan angle member adapted-'tp be attached to the screen through one-of the flanges thereof.

A feature of the invention resides in constructiong the other a'nge of said angle member with a lip issuing outwardly therefrom and in spaced relation thereto.

An object of the invention resides in 'employing in conjunction with said angle memer a plate for attachment to the Window frame having a lip extending outwardly therefrom and spaced from said plat-e, *the lips on said angle member and plate being adapted to be received within the respective spaces between said lips and the structure on which the same are for1ned. Another object of the invention resides in turning over the eXtreme edges of said lips to hol the lips from disengagement.

A still further object of the invention resides in constructing on the flange of the angle member having the lip` formed thereon a protuberance for engagement by `the operator to disengage the lips from one another.

Other objects reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

Where' a permanently attached Window screen is employed an appreciable amount of light is excluded. This vis particularly true Where the Screen covering the entire Wind 'ovvI is used. Furthermore dirt and dust readily accumulate on the screen and upon ltheexterior of the window making it difficult to clean the window yWithout removing the screen. In my invention these diiliculties fare overcome 'due to the fact that the screen may beqnickly and readily detached from 'the structure to which the free end thereof is connected so as to give access to the Window from both sides thereof. Atgthe same vmanner such asis now well known in the art, the particular form illustrated being shown merely for`the purpose of indicating the method of installing my invention thereto.

The frame 10 comprises vertical frame members l13 connected together at their upper'ends by means of a header 14 and at 'their lower ends `by means of the usual Windvv sill 15. The frame 10 is set into the,

opening in the building and is attached to the studdinvg 16 thereof in the usual manner. Frame 10 may be constructed with an outercasing 17 and'with an inner casing 18 and is'provided With'the usual inner stop 19, outer stop 20, and parting strip 21. The

window A may be Afurther provided with the usual window stool 22 and apron 23 forming a part of the interior casing 18 of said window.

The two sashes 11 and 12 are constructed in niuch the s'ame manner. The sash 11 is formed with stiles 24, an upper `rail 25 and a meeting rail 26. while the sash 12 is'similarlyiformed with stiles 27, a meeting rail (not shown) and a lower rail 29. These various stiles and rails are recessed to receive ordinary window panes 30 and 31 which may be mounted therein in the usual manner and sealed through theuse of putty or any other suitable means. The upper sash 11 is slidably mounted between the outer stop 20 and the parting strip 21 while the lower sash 12 is slidably mounted between the said parting strip and V,the inner stop 19. When the sashes `are in closed position the rails 29 are received within the respective guides formed y between the parting strip 21, the stops 19 and 2() andthe stool 22, while the meeting rails of the sash join one another to completely close the window in the usual manner.'

The screen used in conjunction with my invention is preferably of fabric or iiexible' wire and is coiled about a suitable roller and attached at one end thereto. It desired screens may be utilized for both the upper and-lower sashes or for only one of these sashes as the occasion demands. In the drawings I have illustrated a screen 32 in conjunction with the lower sash 12, and a .screen 33 used in conjunction with the upper sash 11. The screen 32 will first be described in detail.

The screen 32 is attached to a roller 34, one end ot which is shown in detail in Fig. 3. This roller is constructed with a bore 35 at one end thereof in which is disposed a rod 36 having coiled about it a helical spring 37. The spring 37 is attached at one end to the rod 36 and at its other end to the roller proper so as to permit of winding up the roller upon holding the rod stationary as is customary with ordinary-window shade rollers. At the eXtreme end of the roller 34 is attached to it a plate 38 which forms a bearing for the end of the rod 36. This plate is secured in position upon the end of the roller through aferrule 39. The extreme end of the rod 36 is formed with a flattened pin 40 which is adapted to be held from rotation and serves to mount the shade in the customary manner. The other end of the roller 34 may be provided with another pin or trunnion (not shown) for supporting the shade roller such as is now 4in common use, or a device similar to or having Similar functions to the rod 36 may be employed for this purpose, either with or .without the helicalspring. out the usual pawls employed for holding the roller in locked position so that when The roller 34 is constructed' with-l the spring 37 is irst tensioned the said roller will'at all 'positions of the sash cause the screen to windjup or coil about the same. In this manner when the screen is attached at its lower end'to the window sill, the same automaticallyvv winds up on the vroller34 as the sash is raisedandflowered to cause the screen at all-times to fill the opening between said sash and sill and to be completely con-l cealed within" the space in which the said roller is mounted when the sash is fully lbers 43 and 44 of a depth equal to the thickness of the said rail. A flange 45 may vbe turnedinwardly from the plate 42 to somewhat stiien'and reinforce the same, though it will become presently apparent that the depth of the'said flangecannot be such as to entirely preclude the flexing of this plate. In an appropriate position on each of the end members `43and 44 and disposed the same distance from the plate 42 are formed two inwardly y extending, facing lugs 46 which maybe formed by pressingr the metal ot the end members 43 vand`44 out of plane thereof. Centrally disposed within these lugs are openings'47 (Fig. 3) which are adapted to receive the Ipins 40. At the vend of the roller where theispringl 37 is located, the opening 'ournaling the same, a circular hole would ave to be employed for this purpose. Such construction being well known in the art has not been illustrated.

The plate 38 situated `at the end ofthe roller 34 is disposed inwardly of the end of the ferrule 39. This provides a space for the reception of the lug 46 bringing the ends of the roller substantially flush with the inner surfaces of the end members 43 and 44 and the end of the pins 40 substantially flush with the exterior surfaces of the said end members. Thispermits of utilizing a screen of substantially the entire width of-the window so as to completely cover the opening through y'the window-and preclude the entrance of insects through the window opening.

The frame structure 41 carrying the roller 34 and screen 32 is mounted onthey lower `rai129 of the window 12.l Thisrail is formed into the proper openings :4T-in said end rncmbers provided for the'reception `of said pins. The screen proper is at. the" same timedisposed between the4 rod 65 and the platev 42. Upon releasingthe framestructure the end members 43 and 44 springback into place so as to hold` thek roller 34 Supported in proper position. The lentire frame structure may be then 'applied to the rail'29 'of the'window sash and'secured thereto lthrough screws 49 insertable through openings`50-in the said plate and end members `an'd'screwed into the sash proper. In the` installation of the'sash a groove l is formed in` the rai'l 29 for the reception of the flange `450i' the frame structure and if desired the frame 41 may be made slightly smaller and the sid'eand ends of said rail may berecessed to receive the plate 42 and the end members 4354 and -44 so as to cause the same to lie Hush with theexterior surface of the sash. When the supporting structure is so installed the end 52 ofthe screen may be projected throughthe open lowerportion `of the rabbet 48 to be extended or retracted therefrom as desired. j

The free end 52 ofy the screen 32 may be I detachably secured to thewindow sill so that when thesash is raised and lowered the said screen may be wound or unwound upon the roller to maintain the space between the rail 29 and the sill 15 covered. Upon the eX- treme end v52 of the said screen is attached an angular attaching strip 53 best shown in Fig. 4 which is constructed wlth a vertical flange 54 and a horizontal flange 55. The extreme-edge of the ange 54 indicated at 56 is doubled back upon itself to receive and hold the extreme end 52 of the screen 32 attached thereto. The other flange 55 of said q attaching member is doubled back upon itselfto form a lip 57 which is spaced from the said ange. Cooperating with the attaching member 53 is another attaching member 58 which comprises a plate 59 adapted to be secured to the window sill 15 througha number of screws 60. This plate is doubled back upon itself along the length thereof to form a second lip 61 spaced from the said plate 59 in a similar manner to the lip 57. The two lips 57 .and 61 may be interlocked by sliding the attaching member 57 along the plate 59 in an outward direction causing the parts to assume the position shown in Fig. 4. For assisting in retaining the lattaching member 53 interlocked with respect to the attaching member 58 the lips 57 and 61 have the extreme edges 62 and 63 thereof turnedv inwardly to prevent the accidental disengagement of the said lipsas long as tension is applied to the screen- 52. Due tothe helicalv spring 37 lthe ysaidscreen is always under tension and the screen remains 'securely attached at its lower end tp the sill proper.

For `facilitatingthe disengagement of the lower end ofthe vscreen the flange 55 .is convstructed with a hump 64 standing upwardly therefrom which may be engaged by the in- Y ger-of the user forassisting in withdrawing the lips 57 and 61 from engagement With one another. 'WhenV it is desired to detach the screen the attaching member 53 is 5 drawn inwardly toward the stool 22 until the edges 62 and 63 are free fromone another. Upon x releasing the screen the tension of spring 37 causes the entire screen to become wound u and wholly confined within the rabbeti48.V

In order to prevent rainv from remaining within the space between the lip 61 and the plate 59 the said plate is constructed atthe bend thereof with a number of holes 70 from which water entering the said space may be drained.

In the attachment of the screen to the win.- dow frame the attaching member 58 is .,10- cated in close proximity to the parting strip 21 so as to cause the screen 32 to liealong the edge of said parting strip, and prevent the intrusion of insects. Als the screen unwinds from the roller 34 the coiled portionthereof becomes smaller is diameter causing the distance between the screen and said parting strip to vary. To overcome this disadvantage I employ'a rod 65 which is attached to the end members 43 and 44 of the frame structure 41 and which guides the movement of the screen 32 so that the same at all portions thereof lies as close to the parting strip 2l as' possible. This rod also serves as a stop for preventing the free end of the screen when released from entering into the rabbet 48 .in such a manner asy to render the same inaccessible and to preclude the withdrawal of the saidv screen from said rabbet when it is desired to put the same into operation.

The screen 33 employed withv the upper sash 11is constructed and mounted in exactly the same manner as the screen 32. For

lustrated in detail. lThis screen is similarly mounted upon a roller 66 carried by a frame structure 67 'similar to the frame structure 41. In thisr device the plate member 68 corresponding to the plate 42 is somewhat shorter than said latter plat-e. 'The reason for this is that the roller 66 instead of being. attached to the rail 25 of sash 11 is attached' lthis reason this structure has not been i1- isc vupon the screen and the supporting-structure therefor in a manner to cause the same to deteriorate and cease to function. The frame 67 is of a width slightly larger than the width of the sash proper andr is received Within the guide formed between the parting strip 21 and the outer stop 20. The frame structure 67 may be secured to the windowv per portion thereof. This rabbet is of such a size as to receive the roller 66 and screen 33 when ythe sash 11 is elevated. When so disposed the platey 68 of the supporting structure 67 covers the rearside of the said rabbet while the end members of said supporting structure corresponding to the end members 43 Vand 44 of the supporting structure 41 cover the ends of the said rabbet.

For the `purpose of providing a tight closure between the two sash 11 and 12 when in open position a sealing strip 7l is employed which is attached to the under side of the meeting rail 26 of sash 11 and which projects up to window pane 31. This stripr serves to maintain the space between the sash closed so as to revent intrusion of `insects there.- throng therefrom and spaced 'from said iiange,` 'n plate for attachment to the member to which the screen is to be fastened, a lip formed along an edge of said'plate and spaced therefrom, said lip extending in the opposite direction from the lip on said angle member2 said lips l being adapted torbe received within the re-4 spective spaces betweenv said lips and the structures from which they issue to hold the screen fastened, said lips having the extreme edges thereof turned over to enga e one another so as to hold vthe lips from isengagement.

ALFRED G. NORDMARKEN.

My invention is highly advantageous-in V that'the same can be constructed at an economical cost. The sheet metalparts forming the supporting structure for yroller can readily be applied to the window frame and sash and `serve to close the rabbet'formed in the sash for the recept-ion of the roller. The end of the screen may be quickly detached or at# tached to the attachingV device so as to bring the same into inoperative or operative position as desired. The guide rod serves to hold the screen close to the parting strip or stop ,so as to effect atight closure and at the same time holds the end of the screen from entering the rabbet a distance sufficient to render the same inaccessible. The device is positive in action and cannot readily 'get out of order.

Changes in the specific form of my invention, as herein described, may be` made within the scope of what is claimed without departing fromthe spirit of my invention.

Having described Ymy invention, what I claim as newy and desire to protect by Letters Patent is: I

l. A fastener for screens comprising an elongated angle member adapted to be se-` cured to the screen through'one of the flanges thereof, the other of the iianges of said angle member havlng alip issuing outwardly i losl
